SPREADER ATTACHMENT FOB, FEBTILIZER-DISTRIBUTERS.

To all whom it may a cam:

Be it known that I, of the United States, residing at Goldwater, in thecounty of Mercer and State of Ohio, have invented certain new and usefulImprovements in Spreader Attachments for F ertilizer-Distributers, ofwhich the following is a specification. 1

This invention relates to manure spreaders or fertilizer distributorsand has special reference to mechanism for repulverizing and spreadingthe material broadcast over a wide area during a single trip of avehicle v having a relatively narrow body.

My present invention is an improvement on the mechanism shown in PatentNo. 648,519, granted to Joseph Oppenheim May 1, 1910, and consisting of'a spreading attachment disposed in rear of the pulverizing mechanismand embodying a plurality of paddles or blades each set obliquely uponthe shaft 'arrying them. The blades or paddles in this patented devicewere of rectangular form and the front edges of the same were straightand practically at a right angle to the material engaged thereby. Asthis material generally consisted of animal excreta mixed with straw 01'similar bedding material, there was a tendency of the long strawy orhairy elements of the mixture to catch on and cling to the forward edgeof a blade or paddle so that the lateral spreading would, at times, beimpaired or prevented, the material, when finally thrown from the blade,dropping to the ground in a straight line.

()ne object of my present invention is to provide a wide-spreadingattachment for fertilizer-distrilmters by which this'objectionableclinging of the long material will be overcome so that this materialalso w ll be distributed and a wider swath covered on each trip of thevehicle than was heretofore possible.

Other objects of the invention are to avoid the lateral flight of thematerial being arrested by theblades, and to provide a blade mount whichwill permit the obliquity of the blade to be varied.

The several stated objects and other incidental objects are attained inthe mechanism illustrated in the annexed drawings, in which- Figure 1 isan end view of my improved spreader in operative position. Fig. 2 is a.

My improvement, which I will briefly call a spreader, may be applied toany form of fertilizer-distrilmter capable of discharging manure orfertilizing material onto its blades.

I have illustrated a portion of a fertilizer distributor in which thefertilizer, indicated at 1, is carried by a feeding apron 2 toward therear end of a wagon body 3 where it is taken up. pulverized anddistributed or thrown rearward by a lower beater or pulverizing anddistributing cylinder 4: and an upper beater or pulverizing anddistributing cylinder 5 set somewhat in advance of the lower beater, theheaters rotating in the same direction. as indicated by the arrows.These heaters or cylinders break up the compact masses of material andthrow the same rearward in a more or less pulverized or disintegratedcondition.

Mounted upon the rear end of the wagon body 3, or upon arms extendingtherefrom, is a spreader shaft 6 which is preferably rotated in the samedirection as the heaters through any preferred mechanism, although thespreader can rotate in either direction by reversing the blades orshaft, provided the working edge is forward. A convenient arrangement,when the spreader runs in the same direction as the boaters, is to drivethe spreader by chain and sprocket gearing from the lower beater asindicated at 7, the beaters being usually driven from the ground wheelsof the vehicle. llpou the. shaft 6, I

.secure a plurality of deflectors. blades or paddles 8 which aredisposed obliquely on the shaft. as shown clearly in Fig. 2, the shaftpassing through each blade near one end thereof. The forward or materialengaging edge 9 of the blade is eccentric to the shaft and describes a'curve on the order of a spiral or involute curve. which extends acrossthe outer end of the blade or that end more remote from the spreadershaft. The blades may be secured to the shaft in any desired manner andl prefer to employ a hub '10 having a circlunfcrculial rib or flange 11which is bolted or otherwise rigidly Fig. 4 shows a modification.

secured to a face of theblade said rib being "inangular relation to thebody of the hub relation along the shaft. A reinforcing strip 13 may besecured to one face of the blade adjacent the rear edge thereof toprevent buckling of the blade, as will be readily understood.

in Fig. 4,1 show a blade inwhich a portion of the Working edge is astraight line 14, which extends obliquely toward the back edge and theouter end of the blade. lt'will be readily seen that in this form, aswell as in the-form shown in the other figures, the working edge iseccentric to the spreader shaft and, instead. of the entire working edgeengaging the material at the same instant, the point of engagement isinitially near the hub or center of rotation of the blade and progressestoward the outer end of the blade as'the same swings upward.

In Figs. 5 and 6, 15 designates the hubs which are secured to thespreader'shaft and 16 designates flanges or disks upon the several hubs,the flanges or disks being concentrio with thehubs but'disposedobliquely thereon. Secured to and projecting from the disk or flange isa' supporting or brace barl'? to which are secured the outer ends ofcurved rods 18, the inner ends of which;

are secured to the disk. It will be noted that the inner ends of theserods are close to gether and that the rods diverge toward their-outerends which are spaced apart an appreciable distance. Each rod forms aneccentric'cuiwe following a spiral path, the radius 0' which increasesas it recedes from the shaft. While this construction does not provide asolid blade it furnishes a very satisfactory deflector. The outerextremities of the rods are bent laterally, as at 19, so that thesupport or brace 17 will be-carried to one side of the plane ofobliquity bf the blade and will be behind the blade the same meets thematerial.v I thus avoid the retention of the long elements of thematerial upon the brace. While. this brace is advantageous in keepingthe outer ends of the rods in position, it is not essential and r may beomitted.

The blades may, of course, be set at any desired angle to the shaft andat any de' sired distance apart'annularly. They may also be fastenedrotatably adjustable to the oblique circumferential rib 11, as will beunderstood upon reference to Figsr3 and (3, so as to have differentpositions of angle or bbliqueness. I prefer to arrange one-halfthe-blades with their working faces inclined toward one side of themachine and the other 1,21a,ezsa

half of the blades inclined-toward the opposite side of the machine sothat the material will be thrown to both sides equally:

I also prefer to arrange the blades so that each blade will be aboutninety degrees behind the adjacent blade immediately preceding it inoperation as this arrangement of the material.

The spreader is preferably rotated at a higher speed than that of thebeaters and is so arranged that the material thrown out 'by the heaterswill come in the path of the spreader paddles and be deflected.laterally. It willbe readily noted that my improved blade ,issubstantially triangular and its working edge is a line or curve havinga progressively increasing radius as it recedes from the center ofrotation of the blade. This edge, conse uently, does not engage thefertilizer abrupt y but meets the same gradually so that the long strawymaterial which would ordinarily tend to cling to the blade and windaround the spreader, will ride upward along the curved or involute edgeand, together with that coming in contact with the obliquely disposedsides ofthe blades, be thrown away. .Moreover, this long material willtravel toward the outer end of the blade where the greatest centrifugalforce is exerted and will be thrown the maximum distance.

apart both along and around the shaft, will consequently also actlaterally on the material coming in contact withthe forward workingedge, and experiments have demon strated that a wider swath. is coveredthan heretofore. p

.By spacing the blades annularly as indicated,adjacent blades engage thematerial successively instead of simultaneously so that each blade willact in advance ofthe neighboring blade and will retire from the zone ofaction before th said neighboring blade becomes a working blade." Thereis a clear lateral space at the sides of each blade, therefore, throughwhich the deflected'material will be-thrown instead of being merely castupon the adjacent blade. It will, of co urse, be noted that the sides ofthe blade are plane or, flat-faced and the plane or fiat-faced sidestrikes the material and A spreader using my improved obliquely disposedblades spaceddeflects itlaterally so that it will be spread broadcast.
